HELLO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! MICROSOFT!!!!!!!!!!!!!!!!!!!!!!!????????????????? ****!!!!!!!!!!!!!!!!!!!!!!!!!!???????????????


It's been 4 years since this tread was started. Where is the fix??????????????????????????????????????????????????

Windows 10 does not let CUDA applications to use all VRAM on graphics card.

I'm a 3D Graphics artist.

I'm using nvidia graphics cards for 3D rendering using CUDA computing.

After upgrading to Windows 10 (from win7). We did not have this issue with windows 7.

The application now reports an amount of unavailable GPU memory that can not be accessed.

This is a very well know problem people in my industry.

This problem occurs using in every nvidia graphics card.

if you have a gpu card with 4GB then you end up having 700MB VRAM unavailable

if you have an 8 GB (1070) card then you end up having 1.3GB VRAM unavailable

if you have a 24 GB Quaddro or Tesla GPU you end up having ~4.5 GB VRAM unavailable

And this limits our workflow.

I doubt if it just effects nvidia cards. I have no knowledge of other manifactureres like AMD having the issue.

GPU oriented computations is mainly done by using nvidia cards. That is by CUDA computing.

I also found an article about Process residency budget regarding the changes in WDDM 2.0

new Windows 10 driver architecture.

Process residency budgets - Windows drivers

I need Windows developer team reply to this issue that we're having with Win 10.

Would be great if we could regain the unavailable memory of our GPU's

My system is

i7 cpu + 32GB ram + nvidia Titan + nvidia GTX 1070 + nvidia GTX 1070 running on win10

I encountered the described issue as well when I installed windows 10 in 2015. I now waited for more than a year in vain for this issue to be resolved.

Issue description:

I paid several thousand dollars for a workstation with multiple GPU for GPU rendering.

All the cards with 6 GB VRAM after windows 10 installation only had around 4.7 GB available to store 3D assets like geometry and textures.

It has now been more than a year and no company involved has been able to work around the issue.

If VRAM needs to be reserved then at least make it a
fixed value and not percentage based on the maximum available memory.

The more memory a card has the more VRAM is reserved. It is not acceptable that customers spend thousands of dollars for new GPU with 12 GB VRAM just to have only around 8 GB useable.

Therefore the hope is that the Microsoft Windows 10 team has a very close look why and how exactly VRAM is reserved.

Microsoft, for goodness sake DO SOMETHING ABOUT IT !!!

I am a long-time Mac user who was about to convert to windows so that I can build a high spec PC and fill it with expensive cuda GFX cards ( for 3D rendering),... But reading this I don't think I'll bother. I'm shocked that you haven't even responded,
let alone fixed the issue.

You are doing nothing to improve the reputation of Windows.

Please let us know what the status of this important fix is
